The business structure that made sense when your company started may not be the structure that makes the most sense today.

Revenue grows. Owners come and go. Payroll expands. Profitability changes. You may begin considering a sale, succession plan, outside investment, or a second location. Meanwhile, tax rules continue to evolve.

Yet many business owners continue operating under the same entity and tax elections they selected years ago without revisiting whether those choices still fit.

As 2026 moves into its final quarter, this is a good time to ask a simple question:

Does the way your business is structured still support where the company is going in 2027 and beyond?

The answer is not always that you need to change entities. In many cases, the existing structure remains appropriate. But reviewing it can uncover tax-planning opportunities, administrative problems, compensation issues, or future transaction concerns while there is still time to address them.

At Apex CPAs, we view entity structure as part of a broader business tax planning strategy, not simply a box that was checked when the company was formed.

Why Fall Is a Good Time to Review Your Business Structure

Business owners often think about entity selection when starting a company.

That is important, but it should not necessarily be the last time the issue is reviewed.

A business that began with one owner and modest profits may look entirely different five years later. What worked for a startup may create unnecessary complexity—or missed opportunities—for a mature company.

Fall is particularly useful for this discussion because you still have time to evaluate changes before the next tax year begins.

That does not mean rushing into a new structure before December 31. Changing how a business is taxed can have significant federal and state consequences, and some changes can be difficult or costly to reverse.

Instead, the goal is to identify whether your current structure still aligns with:

• Current profitability
• Owner compensation
• Payroll
• Number and type of owners
• State tax obligations
• Growth plans
• Capital needs
• Future acquisitions
• Succession planning
• A potential sale of the company

If your business has changed significantly over the last several years, your tax structure deserves another look.

This review can also fit naturally into the financial planning work you are already doing as you prepare budgets, projections, and growth plans for the next year. Our business advisory services are designed to connect these tax questions with the larger financial picture.

Has the Economics of Your Business Changed?

The first question is not, “Which entity saves the most taxes?”

It is, “What does the business look like today?”

Consider a company that began with one owner generating $80,000 of annual profit. Several years later, that same company may have employees, multiple owners, $1 million or more in revenue, significant retained earnings, and plans to expand.

That is a very different business.

The appropriate tax structure can depend on how much the company earns, how profits are distributed, how owners are compensated, whether additional owners may be added, and how much cash needs to remain inside the company.

A growing company may also need better financial systems and forecasting before making structural decisions.

If management cannot clearly see profitability, cash flow, owner compensation, or future capital requirements, changing the tax structure alone will not solve the underlying problem.

For businesses entering another stage of growth, it can make sense to evaluate entity structure alongside a broader strategy for scaling the business.

Is an S Corporation Election Still Worth Considering?

One of the most common entity discussions among closely held businesses involves S corporation taxation.

An important distinction is that an LLC and an S corporation are not necessarily competing legal structures.

An LLC is generally created under state law. Depending on the number of owners and elections made, an LLC may be taxed federally as a disregarded entity, partnership, C corporation, or S corporation.

That means an LLC may be able to retain its legal form while electing S corporation tax treatment if the applicable requirements are satisfied.

For the right business, S corporation taxation can create planning opportunities because business income generally passes through to shareholders rather than being subject to regular federal corporate income tax at the entity level.

But an S election is not automatically the best answer.

Owner Compensation Becomes Important

One reason business owners consider S corporation status is the distinction between wages and shareholder distributions.

That distinction comes with rules.

A shareholder who performs services for an S corporation generally cannot simply eliminate payroll and take all profits as distributions. Shareholder-employees must receive reasonable compensation for the services they perform before non-wage distributions are made.

What constitutes reasonable compensation depends on the facts.

The owner’s responsibilities, experience, hours worked, industry, comparable compensation, and the source of the company’s revenue may all matter.

That means an S corporation strategy should involve more than asking, “How low can I make my salary?”

Compensation should be supportable, documented, and coordinated with the company’s overall tax plan.

Owner wages also affect the owner’s personal tax planning, retirement contributions, payroll taxes, and other parts of the financial picture.

Timing an Election for 2027

If an eligible business wants S corporation treatment to begin January 1, 2027, fall 2026 is an appropriate time to review the decision.

An S corporation election is generally made using Form 2553. For an existing calendar-year business, an election intended to become effective for the following year may generally be filed during the preceding tax year.

Waiting until tax-return preparation is underway can unnecessarily compress the planning process.

Before making an election, owners should understand not only the potential tax benefit but also the payroll requirements, administrative costs, ownership restrictions, and long-term consequences.

Does the Qualified Business Income Deduction Change the Analysis?

The Section 199A qualified business income deduction remains an important consideration for many pass-through business owners.

Eligible owners of sole proprietorships, partnerships, S corporations, and certain other pass-through businesses may potentially deduct up to 20% of qualified business income, subject to applicable rules and limitations.

Current federal law has also made the deduction permanent rather than allowing it to expire after 2025.

That makes Section 199A relevant to long-term entity planning.

However, business owners should not assume one structure automatically produces the largest QBI deduction.

The calculation can be affected by taxable income, W-2 wages, qualified property, the type of business, owner compensation, and other factors.

Income earned through a C corporation does not qualify for the owner’s Section 199A deduction.

S corporation wages paid to an owner also generally are not themselves qualified business income.

This is another reason entity planning should be modeled rather than based on a simple rule of thumb.

Two businesses with identical profits can have very different tax outcomes depending on ownership, compensation, industry, deductions, and other income reported by the owners.

A year-end tax planning review can help identify how those variables interact before decisions are finalized.

What About Illinois Pass-Through Entity Tax?

Illinois adds another layer to the entity discussion.

Eligible partnerships and S corporations can elect to pay Illinois pass-through entity tax, commonly called PTE tax, at the entity level.

The Illinois PTE tax rate is currently 4.95%.

The election can affect how Illinois tax is paid and how owners receive the related state tax credit. It can also be relevant to the federal tax planning of eligible pass-through business owners.

Illinois has removed the prior expiration date for its PTE tax election, so this is no longer simply a short-term planning provision that owners can assume will disappear.

Still, the election should be evaluated each year.

Changes in ownership, income, estimated payments, residency, and operations in other states may affect the analysis.

Businesses with owners or operations across multiple states should pay particular attention to how their entity structure interacts with state and local tax planning.

A tax election that works well for one Illinois-based owner may produce a different result when a company has shareholders or partners residing in several states.

Could Your Structure Complicate Growth or an Eventual Sale?

Taxes are important, but they are not the only reason to review an entity structure.

The business may eventually need to accommodate:

• New owners
• Key employee equity
• Outside investors
• Bank financing
• Acquisitions
• A management buyout
• Family succession
• A strategic buyer
• A private equity transaction

Those possibilities can change what you want from the structure.

For example, a company preparing for outside investment may have different priorities than an owner-operated company expected to remain closely held for decades.

Similarly, a business preparing for a future sale should consider how its entity structure may influence transaction options.

Buyers and sellers do not always prefer the same deal structure. A buyer may favor an asset acquisition while a seller may prefer a stock or equity sale because the tax consequences can be materially different.

Waiting until a buyer submits an offer is often too late to begin thinking about these issues.

Owners who expect a transition in the coming years should coordinate entity planning with their succession planning and broader mergers and acquisitions strategy.

If a transaction is already becoming realistic, a buy-sell due diligence review can help identify financial and tax issues that may affect the deal.

What Should Business Owners Review Before 2027?

An entity review does not have to begin with complicated tax calculations.

Start with what has changed.

Look at the last several years of revenue and profitability. Review owner wages and distributions. Consider whether new owners or investors are likely. Update financial projections for 2027 and beyond.

Then ask whether your existing structure still fits those realities.

A useful review should consider:

• Current entity and federal tax classification
• Number and type of owners
• Owner compensation
• Payroll and employment taxes
• Qualified business income considerations
• Illinois PTE tax
• Estimated tax obligations
• State filing requirements
• Retained earnings and cash needs
• Planned capital investments
• Future ownership changes
• Succession or exit plans

Tax savings should be evaluated alongside administrative costs and operational realities.

A structure that saves some tax but creates additional payroll, bookkeeping, compliance, and professional fees may not produce the benefit an owner expects.

Likewise, the lowest current-year tax bill is not always the best long-term outcome if the structure complicates future growth or a sale.

This is where coordinated financial information becomes especially useful. Businesses that need stronger accounting support before making strategic decisions may benefit from Apex Flex outsourced accounting or an outsourced CFO relationship that brings forecasting and financial strategy into the discussion.

At Apex CPAs, we help business owners evaluate these decisions in context—not simply based on one tax rate or one year’s return.

If your company has grown, become more profitable, added owners, expanded into new states, or started discussing an eventual transition, fall is an ideal time to revisit the structure before 2027 begins.

Key Takeaways

A business entity should not necessarily remain on autopilot simply because it worked when the company was formed.

As a business grows, changes in profitability, payroll, ownership, state activity, compensation, and future plans can alter the tax and financial considerations surrounding its structure.

S corporation taxation may be worth evaluating for some eligible businesses, but it also introduces compensation and payroll requirements that should be planned carefully.

The permanent continuation of the Section 199A qualified business income deduction also means pass-through entity planning remains relevant beyond 2026.

For Illinois partnerships and S corporations, the state’s elective PTE tax remains another planning consideration.

Most importantly, entity structure should be evaluated alongside the future of the business.

If growth, new ownership, succession, or a potential sale may be on the horizon, reviewing your structure before those events become urgent can provide more options.

A good year-end question is not simply, “Can we change our entity?”

It is, “Does our current structure still make sense for the business we are becoming?”
